In the configuration screen for your HDHR, *un*check the free-to-air only box.

I found that some of my QAM channels are setting the encrypted flag,
even when they are not actually encrypted.  If you have that box
checked, and Myth sees that flag, it will not even try to tune the
channel.  Daniel fixed it so Myth would try to tune the channel even
with the encrypted flag, if you uncheck that box.
